Specication of Letters Patent. Patented May 20, 1913, Application med June 1o, 191'2.l serial No. 702,640.

To all lwhom it may concem:

Be it known that I, 'JOHN PETsoHAUER, a subject of the Emperor of Austria-Hungary, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im rovements in Apparatus for Treating Woo of which the following is a specification.

This invention relates to improvements in apparatus 'for treating wood in the log and especially to means for impregnating the fiber with suitable dyes or coloring compound. f

The apparatus hereinafter described in detail consists generally of a supportingl frame on which are adjustably mounted two cylinders one of which serves as a charging retort and the other as an exhausting chamber; of means for clamping the stick or log of wood to be treated; of means for supplying the retort with the liquid dye, and of means for carrying of Athe sap or water which is withdrawn from the log in the operation of my appliance.

My invention' consists of further details whereby the eiliciency of the apparatus is increased. v

In the accompanying drawings which form a part of this application, I have illustrated a preferred construction of my improved apparatus in the following views Figure 1 is aside elevation of the complete apparatus with portions broken away to make certain details clearer; Fig. 2 is Ian enlarged sectional detail of the means for operating one of the clamping heads in the machine; Fig. 3 is a View in end elevation looking from the inside, of one of the clamping heads and end frames surrounding same; Fig. 4 is a side elevation, with portions broken away and other portions shown in section, of the exhausting chamber and adjacent parts of my machine; Fig. 5 is a plan view of one of the gaskets used in my machine, and Fig. 6 is a fragmentary detail of the mountin of a measuring device adapted to facilltate the centering of the log to be treated.

Referring to the details ofthe drawing', 7 represents a frame of' suitable material and proportions supported on legs 7a and having along its top longitudinal rack bars 7".

8 represents the side members of a rectangular frame arranged vertically above the supporting frame 7 and made up of cross bars 8b, 8c, and 8f, rigidly secured to the side members and having reinforcing plates 8a at the lower ends of the side members of the frame, said members 8 affording journals for the spindles of wheels 11. Secured to the frame members 8b, 8c, are blocks 8e, 8d, respectively, which afford a support for parts to be described.

9 represents'the side members of a frame `corresponding generally to the frame 8 just described and consisting of cross bars 9, 9e,

and 9f. Between the cross bars/9, 9f, is a collar 9b formed with an annular flange which lits the corresponding groove in the frame members 9c, 9, so as to permit the collar to turn in said frame members if desired. The frame 9 is also provided with reinforcing and spindle bearing plates 9a to correspond with the plates 8a above described, and journaled in said plates 9a are the spindles or axles of Wheels 10. Surrounded by the collar 9b is the cylinder' chamber 12 formed with an annular flange 12 with an extension 12d at the bottom and with a cover plate 12c at the outer side. The extension 12b communicates with the lower portion of the chamber 12 and is provided with a relief cock 13 by which the contents of said chamber may be discharged. The opening between the chamber 12 and the extension 12b is controlled by a valve 14 the stem of which extends through the chamber 12h and is provided-with a hand operated wheel 14 at its lower end, as clearly shown in Fig. 1. An exhaust pipe 15 which may be suitably connected with any preferred form of pump or pumps is arranged at the end of the chamber 12, and is preferably formed in U-shape or with two parallel branches connected at the top by a valve casing and coupling 15a supplied with a hand operated vvalve 15". This pipe 15 communicates and is connected with the' 15" is of such form that if it be desired to increase the suction applied to the chamber 12 upon opening` said valve both branches of the pipe 15 will be in communication with said chamber, whereas if the valve is closed only one branch of saidpipe will be in operation.

Passing through the center of the chambe 12 is a spindle 17a on the outer end of which is a hand wheel 17 and surroundingI said spindle is n sleeve 16 on the outer end of which is a hand wheel 16a said parts corresponding to the construction shown in detail in Fig. 2 which will be hereinafter particularly described.

Passing through a threaded opening in the top frame member 9e is a screw 19a supplied with a hand .wheel 19 at its upper end and having its lower end engaging the collar 9c so as to prevent upward movement of said collar unless said screw is adjusted to permit such movement, and to provide for the downward movement of said collar upon the screwbeing turned downwardly byv operating the hand wheel .19. The frame 8' is supplied with a screw 20a and hand wheel 20 which lengages the frame members 8f, 8", and .operates in substantially the same manner as described with reference to thel -t-hreaded portions of saidbolts pass through slotted brackets 23 mounted on the frame members 9 and are supplied with adjusting nuts 22 whereby the upper portions of the frames 8 and 9 may be adjusted relative to each other and held in their adjusted position. One of said bolts and connections is clearly shown in Fig. 1, and it will be understood that itsv complementary member will be at the other side of the apparatus. The outer face of the flanges 12a is countersunk annularly to provide a seat for a plate 24 removably arranged on said seat and having a central opening therethrough. Superposed on-this plate is a metal plate 25 in which .there are vertically arranged slots said plate corresponding to the form shown in Fig. 5 and superposed on the plate 25 is a rubber gasket 26 corresponding in shape to the plate 25 but of somewhaty less diameter and having openings therethrough which correspond to the openings in the plate 25. Back of and forming a rigid support, for the plate 24 is a second annular plate 29 which is preferably iixed in the corresponding end of the chamber 12 and is provided with a central opening co-extensive with the opening in the plate 24. The opposite chamber, which for the purpose of description we will call the charging 'chamber of the apparatus, is indicated by the reference character 30 and corresponds in size, shape and general constructionl to the exhausting chamber 12 above described. It is supplied .with an annular fiange 30a on its inner end with a chambered extension 30b at the bot- 31, a valve 32 controlling the opening between the chambers 30, 30". Passing through a central opening in the cover 30c of said chamber is a screw 34b supplied with a hand wheel 34 at its outer end and having a threaded engagement at its inner end with a boss 52b on a plate 52 which corresponds in all essential particulars with the plate 29 of the chamber 12. The collars 34 on the screw 34b are arranged on opposite sides of the cover 30c and the interior of said screw is longitudinally threaded to receive the external threads yon the stem 35a-of the hand wheel '35. The inner end of said stem projects beyond the inner end'of the screw 34b and beyond the inner face of the plate 52 and is supplied with a fixed collar 35. Mounted on top of the chamber 30 and communicating with the interior of thelatter is an auxiliary chamber 36, 36, with the latter portion of which communicates with the upper end of a pipe 37 the opposite end of which communicates with a tank 38 which in the operation of my apparatus is supplied withthe dye or liquid which is to be forced into the log to be treated. This chamber 38 is supplied with a pipe 39 through which air under pressure is conducted to said chamber from any suitable source of supply. The inner face of the chamber 30 is supplied with the plate 40 and gasket 41 corresponding to the similar parts 25,`26,above described in connection with the chamber 12. Said chamber 30 is also supplied with a suitable gage 42 for indicating the liquid pressure within said chamber. The frame members 8b, 8c, and 9c, 9f, are supplied with strain rods 45 having nuts 45a at their upper ends said rods adapted to hold said inner frame rigid. At the bottom of each of the frames 8 and 9,

lis a cross bar 47 the ends of .which a-re secured in brackets 47jl depending from va cross frame. member 48. Mounted on the spindles ofthe wheels 10 and 11 are pawls 10, 11, respectively, the free ends lof which are adapted to engage the rack bar 7b as clearly shown in Fig. 1.

27 represents a log to be treated in my improved apparatus for the central portion of which an adjustable jack 28 is provided, as shown in Fig. 1. To facilitate the centering of the lo to be treated with respect to the two cylinders and especially the gaskets 26, 41, and pla-tes 25, 40, respectively, I provide a marking device shown in elevation in Fig. 3 and in fragmental detail in Fig. 6, the same consistin har 53 having a hub 55 a apted to t over one of the spurs 35h and carrying adjustably mounted thereon a markerv consisting of a crayon 54, a sleeve 54 and a set screw 54b by which the sleeve is adjustably held on the graduated bar 53.

tom with a rear cover 30c with a relief cock In Fig. 5 I have shown a plate or grid of a graduated i consisting .of a circular disk 56 having aseries of openings 56b extending therethrough and provided with a tang 56a by which it may be-conveniently handled.

In Fig. 3 I have shown a. similar* grid 'with the openings different-ly arranged however consisting ofl a plate 43 in the margins of which are notches adapted to lit lugs 30d projecting inwardly from the flange 30, and have also shown a gasket 44 of ring like form placed over the grid 43.

In carrying out my invention I may provide Various grids and gasketshaving openings, dii'erently arranged and of different proportions and of different shapes t-hus providing for the impregnation of the fibers ofthe wood in various forms so that portions will be more deeply colored thanothers and incidentally providing for ,using different colors on thesame logs.

In using my invention for the purposeset forth, the frames 8 and 9 with their attached fdevices, will be separated on the supporting' table or frame 7, and the log to be dyed will be arranged therebetween'and supported on the jack 28. The frames will then be moved toward each other until in contact with the ends of the log which will be sawed to makeas close at as possible with the gaskets 26, 41. The lower ends of the frameswill be pushed along the rack bars so that the pawls 10a, 11a, will preventslipping of said frames and the rds 2l will then be adjusted and their nuts 22 screwed up soas to bring the upper port-ions of the frame as close together as possible, the object being to effect a tight fit between the ends of the log to be treated and the inner faces of the cylinders 12 and 30. The plates and grids 24,.;25, 29, 43, and 44, will be solarranged as to provide direct communication between the ends of .chambers withoutkfair to enter either the logs and the interior of the respective permitting atmospheric of said chambers. rlhe log it will be understood has been centered y with respect to said plates through the engagement of the spurs 35b which will be inserted vin the centers of the log as nearly as possible such centers being found by the use of the gage 53 above described. The air being 'exhausted from` t-he chamber 12 throught suitable pump v'connected with the pipes 15 and the tank 38 being supplied with a suitable dyeing compound and with 'air pressure supplied through the pipe 39, on said compound, the latter will How' through the pipe 37, chambers 36, to the interior of thechamber 30. As the water and sap in the logwill be drawn out through the ex haust action of the partial vacuum -produced in the chamber 12, t-he dye will follow dyes of ter and sap flowing into the chamber 12 will be drawn out through the auxiliary chamber 12b and the exhaust cock 13. The screen or filter made up of the parts 4'9, 50, and 51, will prevent the .clogging of the exhaust pipe 15c communicating with the pipe 15 and the interior of the chamber l2. Any residue of dyeing material left in vthe chamber 30 after the log is dyed may be drawn off through they chamber 30b and the relief cock 3l.

While I have shown and described a form of apparatus for carrying out my invention, I do not wish to be limited to the details of construction set forth as the same results can be accomplished by substantially similar; apparatus, but What I claim and desire to ters Patent, is

`1. In'an apparatus for coloring wood in log form, a main supporting frame, an auxiliary frame mounted on rollers and lonsecure by Letacharging cylinder vertically and laterally adjustable on said auxiliary frame, flexible means for conducting coloring fluid to said cylinder, a second frame mounted on rollers and adj ustably mounted on said main frame, an exhaust cylinder vertically and longitudinally adjustable on said second auxiliary frame, a filter arranged in said exhaust cylinder, means for locking the tops of said auxiliary frames together, means for exhausting air from said exhaustcylinder, means for withdrawing residues from said charging and exhaust cylinders, and means for centering a log relatlve to said cyllnders.
